# Due Gooder vs Codon

The clearest difference is rating: Codon at 5.0 against Due Gooder's 3.3. Codon also leads on update cadence (monthly vs every 4 months). Due Gooder's advantage is ratings volume (47 vs 1) and chart position (#196 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Due Gooder sells 6 in-app purchases, starting at $4.99 per month and Codon sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Codon holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: Due Gooder has 47 ratings behind it against 1, so its average is the more settled of the two.

Due Gooder ships an update every 4 months, Codon monthly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
